Azure Function Deployment is failing

Question

I'm deploying to the Azure Function via yaml pipeline and VS Publish profile, but it's failing the deployment with below non-understandable error.

##[debug]getDeploymentLogs. Data: {"statusCode":200,"statusMessage":"OK","headers":{"content-length":"147","connection":"close","content-type":"application/json; charset=utf-8","date":"Fri, 11 Aug 2023 11:25:43 GMT","server":"Microsoft-IIS/10.0","cache-control":"no-cache","expires":"-1","pragma":"no-cache","x-ms-request-id":"<id>","x-aspnet-version":"4.0.30319","x-powered-by":"ASP.NET"},"body":[{"log_time":"2023-08-11T11:25:38.0464127Z","id":"<id>","message":"Fetching changes.","type":0,"details_url":null}]}

Background - Previously it was working, but I have added ARM deployment for Function App Settings.

        "name": "[concat(parameters('<function-name>'), '/', 'appsettings')]",
        "type": "Microsoft.Web/sites/config",
        "apiVersion": "2022-09-01",
        "dependsOn": [ 
            "[resourceId('Microsoft.Web/sites', parameters('<function-name>'))]"
        ],
        "tags": {
            "displayName": "azwenprd01-devtst-pos-if1101-2-func-AppConfig"
        },

But it failed as I used dependsOn for Function App which I'm not deploying through ARM. I removed dependOn and then ARM template got deployed. After this step I have added FunctionDeployment in my yaml pipeline. But after that, Function deployment were failing which was working previously.

Also, I checked all the files on Kudu. I observed that the ZIP is getting deployed under '\data\SitePackages>' but not getting extracted to wwwroot folder. Also the packagename.txt conatians the older .zip name.

Not sure what's causing this issue. Can we do the clean redeploy to Azure Function ? Or how to forcefully deploy to Azure Function ?

WEBSITE_RUN_FROM_PACKAGE is set to 1.

You can refer my SO thread answer with the ARM code to deploy Function app.
